WINDOW SCREEN MOUNTING Filed May 21, 1952 2 Sheets-Sheet 2 I l "31 21a 2fizz 22 3 Lj Q 131 Fatented June 27, 1933 PATENT orrice WINDOW SCREENMOUNTING Application filed May 21,

This invention relates to window screen mountings and has for its objectthe provision of simple but effective means whereby the screen willalways be centered in the window frame on guides which are permanentlyattached to the outer bead of said frame, the screen being provided withlocking means coacting with said guides under normal conditions andwhich may be quickly detached 1 from said guides to permit the removalof the screen. This object is attained by the mechanism illustrated inthe accompanying drawings.

For the purpose of illustrating the inven- 1 tion, one preferred formthereof is illustrated in the drawings,this form having been found togive satisfactory and reliable results, although it is to be understoodthat the various instrumentalities of which the in- 2 vention consistscan be variously arranged and organized, and the invention is notlimited to the precise arrangement and organization of theseinstrumentalities as herein shown and described except as required bythe scope of the appended claims.

Of the drawings Figure 1 represents a horizontal section through awindow frame provided with screen guides embodying a part of the presentinvention.

Figure 2 represents a front elevation of said window frame with a screenmounted therein and provided with locking means coacting with the guidesof said window frame,

said screen with its locking means forming another part of saidinvention.

Figures 7 and 8 represent a side elevation and plan of the bottom plateof'the locking device.

side elevation of the top plate of said looking device.

Figure 11 represents a side elevation of a portion of the screen frameand showing the outer end of one of the locking devices, and

Figure 12 represents a horizontal section on line 12, 12 on Fig. 2.

Similar characters indicate like parts throughout the several figures ofthe drawings. In the drawings, 10 is a window casing of usualconstruction provided at the rear end with vertical side beads 11between which and the parting beads 12 the upper window sash is adaptedto move.

To the oppositely disposed faces of the side beads 11 are securedT-shaped guide members 13 preferably made of sheet metal folded over toform ribs 14 extending toof the drawings.

The window screen frame 15 has side extensions 16 formed at the rear ofthe vertical side bars 17 of said frame 15 and extending the entirelength thereof, the inner faces of said extensions 16 being'adapted tobear against the rear faces of the ribs 14 of said metal guide members13.

The side bars 17 of the screen frame 15 have embedded therein housings18, each having a slidable locking plate 19 mounted therein.

Each plate 19 has at its outer end an ear 20, the front face of which isalined with the front faces of the extensions 16 and is adapted to bemoved outwardly in the rear of a rib 14.

Each plate 19 is provided also with two ears 21, the rear faces of whichcoact with the front face of a rib 14. p

When the plates 19 are moved outwardly the ears 20, 21 willstraddle theribs 14, as shown clearly in Fig. 3.

The outward movement of each plate 19 is effected by a spring 22 bearingat one end against a wall 23 of housing 18 with the other end of saidspring bearing against a downward projection 24 on plate 19.. p

The housing 18 is made up of a U-shaped bottom member 25 its side walls27.

When the top member 28 of housing 18 is assembled on the bottom member25 the ears 5 26 are bent downwardly into the depressions 29 to lock thetwo members 18 and 25 together.

This top member 28 is provided with an ear 30 which coacts with theprojection 24 to limit the outward movement of the plate 19.

The plates 19 at the right side of screen frame 15 are provided withopeningsBl at their inner ends whereby-the plate 19 may be withdrawnagainst the tension of spring 22 to release the ears 20, 21 fromengagement with the ribs 14 of the guide members 13.

When the various parts/of housing 18 are assembled with theslidableplate 19 therein,

it is inserted in a lateral opening in a side bar 17 of the screen frame15, ears 32 on the top plate 28 limiting the inward movement of saidhousing18.

The cars 20 of plates 19 are disposed in-recesses in thetfront faces ofthe extensions 16 of the side bars 17 of the screen frame 15 so that thefront faces of theseears are substantially flush with the front faces ofsaid side extensions 16.

As these ears 20 bear against the rear faces of the ribs 14 there is nowear upon the wooden frame 15of the screen.

The front ears 21 retain the front faces of the extensions 16 in closecontact with the rear faces of the ribs 14 so that no insects may passbetweenthe extensions 16 and ribs 14.

As shown in Fig. 2 the screen frame is narrower than the window casing,making it possible to adapt the screen frame to windowcasings of varyingwidths or to window casings slightly warped.

v Sometimes these casings are to some extent out of true. that is,theirsi-des are not exactly parallel but even in these cases the screenframe 15 may be fitted readily thereto.

There is always a space between the window casing ,10 and the outersideedges of the extensions 16 projecting laterally from the bars 17 of thescreen frame 15 so that this frame 15 may be moved sidewise to some eX-tent.

. When the frame 15 is mounted on the ribs 14.- the springs 22 in thelocking devices will center the same in the window casing.

' If it is desired to remove the screen frame 15 from the window casing,said frame is moved to the left, as seen in Fig. 2, until the outeredges of side extensions 16 of bars 17 are in contactwith the base ofthemetal guide members 13, the springs 22 in the look ing devices at theleft of the frame 15 being compressed during this movement. r

"The plates 19 of thelocking devices on the righthand bars are thenmoved to the provided with ears 26 on left disengaging the cars 20, 21from the ribs 1 1, and asv soon as this disengagement has been effectedthe right side of frame 15 is moved outwardly beyond the window casingand the frame may then be disengaged from the rib 14 on the left side ofthe window casing.

By a reversal of these movements the screen frame 15 may be mountedagain on the guide ribs. 14.

It is the intension to have the manufacturers of the window casingsfurnish said casings to the builders with the metal T- shaped guides 13mounted thereon to be installed in the building during construction of abuilding, and then when the screens are to be supplied no accuratemeasurements will be required for the reason that knowing the generalwidth of the window casing screens for substantially that width may beforwarded and quickly installed.

This is of great advantage as screen frames may be made in quantitiesand supplied of the general width of any size window and installedquickly, thus saving the labor of men going to the building, takingaccurate measurements of the casings, and then constructing the screenframes inaccordance with the measurement of each particular window.

It is believed that the operation and many advantages of the inventionwill be understood without further description.
